Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 6 in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1 to 6, the utility model discloses a novel electric chuck, which comprises a chuck body 1, wherein the chuck body 1 comprises at least three clamping jaws 2 and a wire coiling 4, the three clamping jaws 2 take the center of the chuck body as the center of a circle, and the angle between every two clamping jaws is 60 degrees; chuck body 1 has jack catch mounting groove 3 and inner groovy 10, and dish silk 4 is installed at the chuck body, specifically is in inner groovy 10, jack catch 2 install on the jack catch mounting groove and with the cooperation of dish silk, dish silk 4 installation opening 43 has, the dish silk on install carousel 6, at least, open logical groove 8 and the cooperation opening 7 that has the long strip structure more than two on this carousel 6, dish silk 4 on open and to have installing port 42, install guide arm 11 on this installing port 7, this guide arm other end extends to and leads to in the groove 8, lead to horizontal and fore-and-aft of groove 8 all be greater than installing port 42.

Wherein, installation opening 43 go up the external power component that has, this power component is including the motor, the output of motor is connected with the output main shaft, the output main shaft is installed on the installation opening, be connected with foot switch on the motor.

The jack catch in this scheme can three or four or six, changes according to the demand.

For convenience of installation and disassembly, the installation opening 42 is a threaded opening, and the correspondingly installed guide rod 11 is a screw rod screwed into the threaded opening.

Six through grooves 8 are arranged, and six corresponding mounting ports are also arranged. The six mode designs, when the carousel moves, the carousel moves earlier, and the inner wall 81 that leads to groove 8 of carousel can contradict on the guide arm, then can promote the rotation of dish silk, and the rotation of dish silk can drive the jack catch activity of adaptation circle silk 4-1 on the dish silk, realizes letting three jack catch do centripetal or centrifugal movement, realizes pressing from both sides the tight purpose or unclamp the work piece, and the jack catch has the prior art with the cooperation of dish silk and does not do the detailed description.

The above scheme is explained in detail: installation opening 43 is mainly used for installing a bearing, can connect the main shaft, this scheme and be connected with the carousel through changeing the cover at the output main shaft, and its tip passes through bearing arrangement installation opening 43, and this scheme has mainly increased a bearing, and the connection of output main shaft is more firm like this, can not take place to rock during the operation. The ratio of the transverse length of the through groove 8 to the transverse length of the guide rod 11 is 4-6: 1.

In order to further achieve the effect of speed reduction, the outer end of the rotary table 6 is fully distributed with teeth 61 to form a toothed disc, the outer part of the rotary table 6 is matched with a gear ring 5, the inner wall of the gear ring is specifically provided with teeth 51 meshed with the toothed disc, and the gear ring 5 is arranged on the inner wall of the chuck body.

To reduce noise, a cushion pad is provided on the inner wall 81 of each through slot 8.

In order to improve the strength and the high toughness, the chuck body is made of nodular cast iron or forged steel.

In this scheme, having add the speed reduction structure when starting, can having reduced the direct collision between the part, life and the security of using improve, still having add the ring gear externally simultaneously, having carried out the speed reduction of second way, improve the reliability of product greatly, it needs to point out that the quantity of tooth 51 on the ring gear is greater than the quantity of the tooth 61 of carousel 6, and concrete numerical value is one, is formed with the planet effect of slowing down.

The electric chuck of this scheme, the security is high, specifically mainly is embodied, adopts foot switch, can the rotation of direct control motor, and trampling switch can adopt transformer output voltage to be 24V, forms safe voltage. If misoperation occurs, the foot switch can be controlled at any time.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
